SURRY, Maine — An 86-year-old man died Sunday in a fire that destroyed his farmhouse on the Surry Road.

Howard Young lived alone in the home, Stephen McCausland, spokesman for the Maine Department of Public Safety, said in an email.

Investigators from the Maine fire marshal’s office were on the scene Sunday morning, according to Surry fire Chief Richard Black. The cause of the fire had not been determined by late Sunday afternoon.

Firefighters were called about 5 a.m. to the farmhouse, Black said. The blaze was reported by a passerby.

When firefighters arrived, there was heavy smoke coming from one side of the building and flames shooting out the other side and out of the roof, he said.

Once firefighters were inside the building, they found Young in a bedroom, the chief said.

Young was taken to the state medical examiner’s office in Augusta to determine his cause of the death.

The farmhouse is one of the oldest structures in town. The way it was constructed made fighting the fire challenging, and the fire spread quickly, Black said. It took more than two hours to bring it under control so firefighters could enter the building.

Mutual aid was provided by firefighters from Ellsworth, Trenton, Lamoine, Orland, Sedgwick and Blue Hill.
